Upgrading iPXE booting Windows 7 to Windows 10

[netwerk]

I have tested diskless Windows 10 RTM on several different machines now and they all behave similarly, regardless of hardware. Install goes on no problem but when booting the machine it either crashes or the network card shuts off (probably a crash as well).

Windows 10 "insider" build 10130 is the last build where booting diskless worked for me. The next build update (don't remember the build number) broke the diskless booting and the final release is the same.

Anyone have any ideas? I haven't been able to debug the boot process. I wonder if there is some way to make it log to a local drive while booting diskless. Serial port debug maybe? Hmmm... I have read about the "LWF" network driver binding (or somesuch) causing issues. Something about it running during boot and needing to unbind it from the iscsi NIC. I wonder if that's the case here.
